Simple Validation question from newbie

[benLL]

Hi,
I am trying to set a Validation rule in Access 2013.
I want to limit the data input as a number range to between 1 and 3.
Every syntax I have tried comes up with (missing operator) in table level validation expression.
It may be a simple answer, but its bugging me. Going through nicotine withdrawl does not help.
Thanks in advance.

You can put a check constraint on a field using this sort of command in the immediate window.
However, I have seen no simple way to know what constraints exist. So if you add such a constraint document it well.

Here I am putting a check constraint (check this before adding a record to this table) to restrict InputRange to 1,2 or 3 on Table JPersons

CurrentProject.Connection.Execute "ALTER TABLE JPersons ADD CONSTRAINT chk_Range  CHECK (InputRange>=1 and InputRange <=3);"

I used this code to Drop the constraint

CurrentProject.Connection.Execute "ALTER TABLE JPersons DROP CONSTRAINT chk_Range"

Also, I just added the validation rule to the table as per the attached jpg.
And an example of the validation error that results if you attempt to enter a value outside the permitted range.
